Brief Summary:

This is an observational study in which data from people with hemophilia A who decide on their own or by recommendation of their doctors to take Jivi are collected and studied. In observational studies, only observations are made without specified advice or interventions.

Hemophilia A is a genetic bleeding disorder that is caused by the lack of a protein in the blood called "clotting factor 8" (FVIII). FVIII is naturally found in the blood where it causes the blood to clump together to help prevent and stop bleeding. People with lower levels of FVIII or with FVIII that does not work properly may bleed for a long time from minor wounds, have painful bleeding into joints, or have internal bleeding.

The study treatment, Jivi (also called damoctocog alfa pegol), is already available for doctors to prescribe to people with hemophilia A to treat and prevent bleeding. It works by replacing the missing FVIII, or the FVIII that does not work properly.

People with hemophilia A need frequent injections of FVIII products into the vein. So called standard half-life (SHL) products need to be given 2 to 4 times a week for the prevention of bleeding. In recent years, new products like Jivi called extended half-life (EHL) products have available. These products last longer in the body so that they require to be given less often with injections up to every 7 days. Thus, these treatments may be easier and more comfortable to stick to in daily life. There is no general plan concerning the best amount of treatment and the frequency of injections for the prevention of bleeding, since the severity may be different and individual risk factors have to be considered. Doctors often decide on a treatment plan based on patient's disease and response.

Clinical studies have already shown that people with hemophilia A benefit from the treatment with Jivi. However, there are no data available coming from the real-world about how well Jivi works to support joint health, measured by ultrasound (US) examination and HEAD-US score.

In this study, researchers want to learn more about how well Jivi works if used for prolonged periods of treatment under real-world settings to prevent problems with joints in people with hemophilia A. How well it works means to find out if participants' joints status can be improved by treatment with Jivi.

To do this, researchers will collect data about participants' joints status by

  • making images of participants' joints by using sound waves (ultrasound), and
  • using HEAD-US score after 24 months of treatment with Jivi. The researchers will then compare these data to the participants' joints status before treatment start with Jivi.

Besides this data collection, no further tests or examinations are planned in this study.

Some participants in this study will already be receiving treatment with Jivi as part of their regular care no more than 12 months. And some participants will start to take Jivi in this study as prescribed by their doctors during routine practice according to the approved product information.

The researchers will collect data from each patient for a period of 26 months after initiation of the Jivi treatment.

There are no required visits or tests in this study.

Hemophilia A patients
Hemophilia patients who had initiated damoctocog alfa pegol treatment.
Drug: Damoctocog alfa pegol (Jivi, BAY94-9027)
Intervention is given as part of routine medical practice.




Primary Outcome Measures :
  1. Occurrence of an unchanged or decreased HEAD-US score at 24 months after treatment initiation with damoctocog alfa pegol [ Time Frame: 24 months ]
    The Hemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) score is based on the three markers for the main joints (knees, elbows, ankles): synovitis (score: 0-2), cartilage (score: 0-4), subchondral bone (score: 0-2).


Secondary Outcome Measures :
  1. Occurrence of an unchanged or decreased HEAD-US score at 12 months after treatment initiation with damoctocog alfa pegol [ Time Frame: 12 months ]
  2. Occurrence of a decrease in joint ABR together with a decrease in HEAD-US score 12 and 24 months after treatment initiation with damoctocog alfa pegol [ Time Frame: 12 months and 24 months ]
    ABR: Annualized bleeding rate

  3. Change in the number of target joints (as defined by ISTH) 12 months and 24 months after treatment initiation with damoctcog alfa pegol in relation to HEAD-US score [ Time Frame: From baseline to 12 months and 24 months ]
    ISTH: International Society on Thrombosis and Hemostasis

  4. Change in HEAD-US score and HJHS score 12 months and 24 months after treatment initiation with damoctocog alfa pegol [ Time Frame: From baseline to 12 months and 24 months ]
    The Hemophilia Joint Health Score (HJHS) measures joint health, in the domain of body structure and function (i.e. impairment), of the joints most commonly affected by bleeding in hemophilia: the knees, ankles, and elbows.

  5. Change in physical activity (IPAQ-SF) 12 months and 24 months after treatment initiation with damoctocog alfa pegol by categorized HEAD-US score change [ Time Frame: From baseline to 12 months and 24 months ]
    The International Physical Activity and sports short form (IPAQ-SF) questionnaire consists of 7 items and will ask about the time one spent being physically active in the last 7 days.

  6. Change in pain (Visual Analogue Scale) 12 months and 24 months after treatment initiation with damoctocog alfa pegol by categorized HEAD-US score change [ Time Frame: From baseline to 12 months and 24 months ]
    Pain Visual Analogue Scale (VAS) score categorized as "no pain (0-4)", "mild pain (5-44)", "moderate pain (45-74)" and "severe pain (75-100)" vs. HEAD-US score change categories (worsened, unchanged, improved).
